摘　　要：根据某低速柴油机曲轴齿轮装配的实际工况,建立齿轮及过盈轴的三维有限元模型,对曲轴齿轮过盈装配进行分析。研究了不同装配过盈量下齿轮的应力分布情况,得出齿轮装配过盈量对齿轮受力影响的规律;并通过与增加凹槽模型的计算结果的对比,得到改善齿轮应力分布的方法。According to the actual working conditions of crankshaft gear assembly of certain low-speeddiesel engine, the three-dimensional finite element model was set up, and the interference fit was ana-lyzed. The stress distributions of the gear under different interference values were studied, which lead thediscipline of the influence of gear assembly interference on the force of gear. Together with the compari-son with the results of adding groove model, the methods which improve the stress distribution of the gearwere obtained.
